Problem with imported SVG - cannot convert curves to mesh properly
There is a hidden extra vertex in your curve object that confuses curve behavior.
The vertex is located on the left from the top right vertex in the S, marked with the green square in the picture. It is actually selected (and should look white) but because it is behind another vertex you can't see it.
Click on the location twice, so you won't see a white selection (but in the bottom right corner it still says: &quot;Vert 1/414&quot;) Then press X or Del and choose Dissolve Vertices. This should resolve your issue.
